The Hydraulic Institute has updated the ANSI/HI Standard for Rotary Pumps Tests version 2000. It has also debuted ANSI/HI 3.6 - 2010, Rotary Pump Tests. This updated standard is applicable to industrial/commercial rotary positive displacement pumps, according to a news release from the Hydraulic Institute.

It includes detailed procedures on the set up and methods for performing hydrostatic test and performance tests of such pumps. ANSI/HI 3.6 is immediately available for purchase HI's online storefor $75.

Significant updates include complete reformatting of the Standard for easier reading; use of larger graphics and figures and more detailed descriptions. Also included is an equation for pump output power.

The new Standard provides most current testing procedures and acceptable deviation of dependent test quantities from specified values for Type III and Type IV testing and is intended for use by all testing facilities. The objective of ANSI/HI 3.6 - 2010 is to establish a uniform demonstration of a pump’s ability to perform satisfactorily both mechanically and hydraulically.
